The South Portland Planning Department and Age Friendly South Portland will host a presentation on accessory dwelling units at 6:30 p.m. April 25 at the main branch of the public library.

The City Council passed an ordinance in November that permits accessory dwelling units, or ADUs, on single-family lots to align itself with state affordable housing laws that take effect later this year. ADUs are small housing units located on residential lots, often referred to as in-law apartments.

The Planning Department will provide information on the law change and how ADUs may become easier and more affordable to build.

For more information, contact Community Planner Eli Rubin at erubin@southportland.org or 767-7633.
